Brittle and resilient aren't really two competing labels for the same thing -- they're two halves of one move. "Brittle" is the negative diagnosis of a current state; "resilient" is the positive improvement target the diagnosis is arguing toward. You make something less brittle by increasing resilience, redundancy, flexibility, or slack.
The test: is the diagnosis paired with a target state?
This is an antonymic reframing pattern, not a same-axis contrast: naming what's currently brittle and naming the resilient target state are two halves of one complete business move. A diagnosis that stops at "this is brittle" is only half the useful sentence.
In an incident postmortem, naming the nightly data pipeline as brittle -- it has no failover if the single upstream feed goes down -- is only half the write-up; pairing it with "the target state is a resilient pipeline with a backup feed and automatic retry" completes the antonymic move from diagnosis to improvement goal.
"...so we should make it less brittle by adding a second reviewer" turns a bare observation into a proposal someone can approve or fund.
The common mistake: stopping at the diagnosis, or skipping it entirely
The mistake is stopping at the diagnosis -- naming the resilient target state is what turns an observation into something a decision-maker can act on. It's also a mistake to jump straight to "resilient" without ever naming what's currently brittle, since that skips the evidence that makes the target state worth funding in the first place.

Practice scenarios
Practice using brittle in situations like:
- pairing a brittle diagnosis with a named resilient target state in a postmortem or proposal
- catching a write-up that names a problem as brittle but never proposes the resilient fix
- avoiding a proposal that jumps to "resilient" without first naming what's brittle
Useful practice phrases:
- "[X] is brittle because [dependency]; the target state is a resilient [X] with [fix]."
- "...so we should make it less brittle by [redundancy/cross-training/backup]."
- "Naming brittle without a resilient target is only half the write-up."
